Waste #
To understand what food waste avoidance strategies people are already employing.
What we want to be able to say
that people are moving towards wasting less, and that there is desire for programs that support that move.
Behavior and longform steps#
Below you can see how many respondents are actively trying to reduce food waste as well as a table showing the steps that those who are trying to reduce waste are taking.
| region | education | income | age_group | SASSY | politics | state | sex | Can you tell us a bit more about the steps you are taking to reduce food waste? | |
|---|---|---|---|---|---|---|---|---|---|
| Loading... (need help?) | None | region | education | income | age_group | SASSY | politics | state | sex | Can you tell us a bit more about the steps you are taking to reduce food waste? |
Steps taken#
The next table show the weighted average engagement of respondents with specific behaviors. Resondents were given a 7-item likert scale for which to answer from Every time to Never, the table below showes the weighted average of normalized responses. That is, 1 represents an average responses of Every time, whilst 0 represents an average response of Never.
| We all do different things when it comes to shopping for food and cooking How often do you do the following behaviors? | |
|---|---|
| I make a grocery list when I go grocery shopping | 0.699223 |
| I stick to use-by/best-before labels | 0.664936 |
| I adjust plans for what I am cooking based on what I have in the fridge | 0.672528 |
| I compost food scraps / other food waste instead of putting it in the garbage | 0.296812 |
| I check my fridge and pantry before buying food | 0.752424 |
| I pack my fridge to the brim | 0.394508 |
| I make a point to use up food that is about to expire | 0.717997 |
Now let’s look at the correlation plot of steps taken and demographics

Reasons for waste reduction#
The next table show the weighted average response of participants beliefs around why reducing food waste is important.
Resondents were given a 7-item likert scale for which to answer from Strongly agree to Strongly disagree, the table below showes the weighted average of normalized responses. That is, 1 represents an average responses of Strongly agree, whilst 0 represents an average response of Strongly disagree.
| How much do you agree or disagree with the following statement? | |
